Application iled November l2, 1900. Serial No. 36.199. (No model.)

To @ZZ whom it may concern.-

Beit known that I, OSCAR ANDERSON, a citizen of the United States, residing at Kearney, in the county of Hudson and State of New .Iersey, have invented certain new and useful Improvements in Centrifugal Creaming Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of centrifugal creamers represented by those shown in my prior patents, No. 547,367, of October l, 1895, and No. 576,994, of February 16, 1897, the objects of the construction herein shown being to provide a partition having protuberances each with a lateral opening extending from base to apex thereof and forming both cream and milk passages; to provide a plurality of such partitions separated by stays or ribs; to secure a perfect and complete separation of cream from the blue or skim milk, and to obtain other advantages and results, some ofwhich may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved centrifugal creaming device and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and iinally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the severalfigures, Figure l is a side elevation, partly in vertical central section, of the separator embodying the in vention. Fig. 2 is an enlarged detail section showing the construction of a certain cylindrical partition more clearly. Fig. 3 is a section on line sc, Fig. 1, showing the arrangement of a concentric series of partitions of the novel construction; and Fig. 4 is a section taken at line y of Fig. l. Fig. 5 is a side elevation of said cylindrical partition detached from the bowl. Fig. 8 is a view of a portion of the same, on a somewhat enlarged scale; and Figs. 6, 7, and 9 are sectional views, Fig. 6 being taken at y', Fig. 7 at and Fig. 9 at e.

In said drawings, a indicates an ordinary rotary shaft having a bowl I), seated at the top, the bowl and shaft being of any suitable construction and operated by any of the usual means commonly employed for the purpose. Within said bowl is a series of concentric partitions c c c c of varying diameters in plan and disposed one within another, each having circumferential projections or stays @adapted t0 engage the adjacent walls of the next partition in order, the stays of the outermost partition of the series bearing against the inner side walls e of the bowl b, as will be understood. These stay projections may be of any suitable construction; but I prefer to give said stays CZ an oblique or spiral arrangement with respect to the bowl, whereby the milk to be separated is prevented from taking a direct upward course through the bowl. Said stays d may be continuous ribs formed by wires soldered in place or may be of any other suitable construction.

The circumferences of the partitions e are perforated, as at fff, and at each perforation the surrounding metal edges are bent preferably inward at one side of the perforation and outwardly at the opposite side. This forms virtually oppositely-projecting protuberances g on opposite sides of the partition, each being cut away or apertured laterally from its base to its apex.

By my construction but a single perforation in the side of a protuberance is secured and which affords simultaneous passage for the blue milk and cream in opposite directions.

The sheet-metal cylinders or partitions are thus provided with a great number of projecting protuberances laterally open and which serve to guide the blue milk and cream on their respective courses without interference. This was also accomplished by my prior patents above referred to but the speciflcconstruction therein shown involved two separate perforations at the apex and base, respectively, of aprotuberance and forming in- IOC dependent passages for the blue milk and cream. The present construction facilitates manufacture and can be employed to great advantage in some cases.

In operation the whole or new milk is fed into a vertical tube h at the axis of the bowl, through which it passes downward into a bottom chamber t', formed by a horizontal partitionj, near the bottom of the bowl. After spreading horizontally in said chamber the milk flows up through perforations or passages p in said partition and passes between the partitions, where its course is broken, and it is brought into contact with the obstructing protuberances. The fine particles of cream are gathered by the obstructing surfaces and are led by the inclines inward toward the center of the bowl, and the blue milk passes outwardly as the fluid gradually moves up ward toward the exits mfor the cream and blue milk.

Having thus described the invention, what I claim as new is- 1. In a centrifugalseparator, the combination with the bowl, of a partition of sheet metal having a multiplicity of perforations disposed at Various separate points through said partition and having the metal at cach perforation bent to form a local protuberance, the perforations extending from the apices to the bases of the protuberances, substantially as set forth.

2. In a centrifugal creamseparator, the combination with the bowl, of a sheet-metal partition arranged within said bowl and having lateral protuberanoes disposed at separate points over the body of the said partition, the said partition being bent at said points to form lateral protuberances and perforated to permit an outflow of blue milk and an inflow of cream, the cream and. blue-milk passage of each protuberance uniting at one side of the said protuberance, substantially as set forth.

3. In a centrifugal separator, the combination with the bowl, of a series of concentric metal partitions arranged within said bowl, a space for the fluid being formed between the adjacent partitions, said partitions having protuberances extending into the said spaces, the said protuberances having each at one side a cream and blue-milk passage extending from the apex to the base of the protuberance, substantially as set forth.

4. In a cream-separator, a partition adapted to be arranged within a rotary bowl and having a multiplicity of perforations, the metal at each perforation being bent at one side of the perforation inward and on the opposite side outward, to form oppositely-extending protuberances with inclined surfaces, su lostantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of September, 1900.

OSCAR ANDERSON.
